The schema management code used by the Landscape project has been
included under storm.schema, allowing to define Schema objects for
creating, dropping, clearing and upgrading database schemas across
multiple databases. The patch system is file-based, i.e. each database
patch is defined in a separate file inside a Python module directory.

See storm.schema.patch.PatchApplier and storm.schema.schema.Schema for
more details.

When a TimeoutError is raised it now includes a description
explaining how the exception was triggered. This should help make
it easier to reason about timeout-related issues. Several
docstrings related to timeout tracing machinery have been added or
improved, as well.
